Four young Americans who've each suffered a Traumatic Brain Injury emerge from their comas at a New Jersey medical facility. Their eyes may be open, but now the real challenge for each of the patients, their families, their doctors and their therapists begins. Brain healing isn't predictable, we're told, and certainly is not guaranteed. So with each 'major' step forward that is observed (opening one's eyes, bending a thumb upon command, vocalizing a word, answering a question correctly) comes a sense of jubilant relief and hope from the families of these patients, but as we soon see, the more a patient progresses, the more difficult things can be for all involved. Moments of faith & hope contrast with disappointments & frustrations, moments of confidence with moments of doubt. It's difficult to watch, and unimaginable to have to ever live through.
Thirty distinguished astronomers are visited at their observatories throughout the world in this comprehensive report of astronomical theories, research, and discoveries.
Is building our own starship Enterprise possible? Will we ever travel between the stars as easily as they do in Star Trek? JJ Abrams' new feature, Star Trek Into Darkness, hits the screen in a golden age of scientific discoveries. HISTORY is there, giving viewers a deep look behind the scenes, on the set, and into the science–amazing new exoplanets, the physics of Warp drive, and the ideas behind how we might one day live in a Star Trek Universe.
The Scorpions belong to the oldest land-based arachnides with over 1800 different species known to exist. Usually, they do not surpass the size of 10cm in length, but exceptions are know, such as the Emperor Scorpion (Pandinus imperator) which can grow up to become over 20cm in size. Scorpions are mostly active at night and hide away during the day. Take a look into the live of these amazing creatures!
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?
Prof. Jim Al-Khalili tackles the biggest subject of all, the universe. Through a series of critical observations and experiments that revolutionised our understanding of our world Jim guides us through the greatest cosmic detective story of all. He takes us from the beginning of the universe to the end time and answers the question: where did the universe come from and how will it end?
A celebration of the universe, displaying the whole of time, from its start to its final collapse. This film examines all that occurred to prepare the world that stands before us now: science and spirit, birth and death, the grand cosmos and the minute life systems of our planet.
Fascinating -- and unintentionally funny -- experiments at Austria's famed Institute for Experimental Psychology involve a subject who for several weeks wears special glasses that reverse right and left and up and down. Unexpectedly, these macabre and somehow surrealist experiments reveal that our perception of these aspects of vision is not of an optical nature and cannot be relied on, while the unfortunate, Kafkaesque subject stubbornly struggles through a morass of continuous failures.
Sir David Attenborough investigates the discovery of a lifetime: the giant skull of a prehistoric sea monster, known as a pliosaur – the Tyrannosaurus rex of the seas!
An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.
A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.
Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.
Wildlife photographer Richard Sidey joins an international team of whale research scientists in Antarctica to document their work on how Humpback Whales are adapting to a changing ocean.
Follow leading scientists around the world and to the edge of the universe on their quest to solve one of the greatest mysteries of the universe, the mysterious invisible “dark matter.”
Richard Feynman was a scientific genius with - in his words - a "limited intelligence". This dichotomy is just one of the characteristics that made him a fascinating subject. The Pleasure of Finding Things Out exposes us to many more of these intriguing attributes by featuring an extensive conversation with the acclaimed Nobel Prize winner. During the course of the interview, which was conducted in 1981, Feynman uses the undeniable power of the personal to convey otherwise challenging scientific theories. His colorful and lucid stories make abstract concepts tangible, and his warm presence is sure to inspire interest and awe from even the most reluctant student of science. His insights are profound, but his delivery is anything but dry and ostentatious.
Let There Be Light follows the story of dedicated scientists working to build a small sun on Earth, which would unleash perpetual, cheap, clean energy for mankind. After decades of failed attempts, a massive push is now underway to crack the holy grail of energy.
During the last Ice Age, millions of large animals roamed the Earth, from wooly mammoths and giant sloths to cave lions and saber-toothed cats. But as the temperatures rose, three-quarters of these species died out. What happened? Can environmental changes alone really explain this mass extinction, or did humans - who at this very time were beginning their conquest of the planet - play a key role? To find out, researchers around the world are hunting and studying fossils in their search for answers to solve the mystery of the Ice Age giants.
A scientist explains how the savagery and efficiency of the insect world could result in their taking over the world.
Commentator-comic Bill Maher plays devil's advocate with religion as he talks to believers about their faith. Traveling around the world, Maher examines the tenets of Christianity, Judaism and Islam and raises questions about homosexuality, proof of Christ's existence, Jewish Sabbath laws, violent Muslim extremists.
